Campaigns/Missions & Other SPOILER Questions.

[soclean]

This may be a real stupid question but i have been awnsering the cb radio and getting those loads to haul instead of going to the warhouses but i cant seem to find the trailers where it says they are and if i do i have a real hard time finding where to deliver them is any one else having this problem or does any one ha ve any easier ways? I have the gps but it seems to run me in circles

I have been awnsering the calls on the phone or cb radio and it take forever to find the trailer or find where to deliver it i know it will say oakland but i drive all over oakland trying to find the point to deliver and it takes forever if i ever find it is this normal and is there any easier ways i have the gps but it runs me in circles example i was supposed to pick up a octopus adnt take it to san jose never could find the load
